BIRT EDWARDS, OF MONTEZUMA, INDIANA.

RADIATOR.

Application filed February 26, 1923.

To all whom it may concern:

Be it known that I, BIRT EDWARDS, a citizen of the United States, residing at Montezuma, in the county of Parke and State of Indiana, have invented new and useful improvements in Radiators, of which the following is a specification.

My present invention has reference to a radiator for automobiles or other internal combustion engines.

An object of the invention is to produce aradiator of this character in which the core thereof is made up of removable and interchangeable water columns.

A further object is to produce a radiator having the heads of the shell thereof shouldered, the vertical walls whereof being provided with openings for the reception of nipples designed for frictional engagement with smaller openings or nipples carried by core sections, each of which being of a similar construction whereby the same are interchangeable, and also wherein any one of the sections may be removed should an injury he inflicted thereon and the nipples receiving the same plugged, so that delay in driving the machine when injury occurs to the radiator thereof will be obviated.

A further object is to produce a radiator for internal combustion engines in which the core thereof is made up of removable water columns having interfitting elements at the inlet and outlets thereof, and likewise hav ing interfitting elements between the inner core sections and the upper and lower heads of the radiator, and wherein, simple, spring influenced means is provided for holding the core sections assembled for proper association with each other and with the heads of the radiator shell.

To the attainment of the foregoing and other objects which will present themselves as the nature of the invention is better understood, reference is to be had to the drawings which accompany and which form part of this application.

In the drawings Figure 1 is a front elevation of a radiator in accordance with this invention.

Figure 2 is a rear elevation thereof.

Figure 3 is a sectional View approximately on the line 33 of Figure 1.

Figure 4 is a sectional view approximately on the line 4-4 of Figure 1.

Figure 5 is a front elevation of the radiator shell with the core removed.

Serial No. 621,273.

Figure 6 is a perspective view of one of the core sections or water columns.

As is usual, the shell 1 of my improved radiator has a water head 2 at the top thereof and a similar head 3 at the bottom thereof. The head 2 is provided with the usual water inlet spout closed by a cap in the usual manner, and of cou1se, the side walls connect the upper and lower heads. In the present instance the heads from their outer and confronting corners are shouldered to provide horizontal walls 4 and vertical inner walls The vertical walls, at equi-distantly spaced intervals have preferably centrally and longitudinally arranged therethrough round openings and in each of these openings there is received a short pipe sieeve 6. There is preferably a ground joint connection between the sleeves and the openings in the said walls 5 so that an effective water-tight joint is provided between the said openings and the pipe members. The sleeves may be and preferably are flared from the center to the ends thereof to fuither insure a tight connection between the same and the walls provided by the openings. If desired, the pipe sections 6 may be screwed in the openings, but i have found that an effective and water-tight joint may be provided by the construction as above described.

The water columns which provide the core of the radiator may comprise any desired number of series, each, however, being of a similar construction. in the illustrated embodiment, two such series are shown. Each water column 7 has its ends of substantially rectangular formation, and for the sake of convenience the said ends will hereinafter be referred to as the heads of the columns. From the heads the sides of each column are bent, cast or otherwise formed to provide inwardly and outwardly inclined passages which, of course, extend the entire length of the columns. For distinction the zigzag sides of the columns are indicated by the numeral 8, and the passages 8 on one side of each column is separated from the passages on the opposite side of the said column. The heads 9 and 10 of the columns communicate, however, with each of the side passages. The heads are provided with round openings 11 which are preferably slightly in'lined or beveled inwardly, the openings in the inner series of columns receiving therein the sleeve or pipe sections 6, and the openings on the outer columns in both of the series there are headed securing means. Such means comprise shanks provided with heads 16. The shanks 15 are received in suitable sockets 17 in the horizontal walls 5 of the water heads 2 and 3 of the radiator, springs 18 drawing the said shanks inwardly of the sockets so that the heads 16 thereof will contact with the outer series of water columns to force the same against the inner series and the'latter against the walls 5 of the Water heads 2 and 3. The heads 16 of the securing elements are cut away in a line with one or the sides of the shanks 15, St that by turning the said elements the straight walls 19 provided by the heads will be arranged to a-pos'ition to permit of the withdrawal of the water columns from the radiator shell.

It is thought from the foregoing description that the advantages and novel features of the invention will be readily apparent.

I desire it to be understood that I may make'such changes in the constructionand arrangement of parts as fall within the scope of my claim.

Having described the invention, I claim A radiator comprising a shell provided with upper and lower water heads, each of which having a depression at their outer confronting corners to provide a vertical wall and a horizontal wall,-the-vertical walls having spacedopenings therethrough, short pipe sections received in said openin 's and projecting therefrom, a core comprising series of separable water columns to be receivedi'n the depressed portions of the water heads, the ends oI each of the columns being substantially rectangular and the sides thereof forming separable 'zig-zag water passages which communicate with said ends, said ends having openings therethrough whereby the inner series of the columns 'receive the short pipe sections therein,'other short pipe sections arranged in the openings of the inner and outer series of columns, plugs closing the openings on the outer face of the outer series of columns, and spring influenced means revoluble for contac'zting engagement with the outer series of columns for forcing the: same against the inner series and the inner series against the inner 'walls of the depressions in-the heads oftheshell.

In testimony whereof I aifix my signature.

BIRT EDWARDS.
